  "Description": "The ability to tune models is important. 'finetune'\nenhances the 'tune' package by providing more specialized\nmethods for finding reasonable values of model tuning\nparameters.  Two racing methods described by Kuhn (2014)\n<doi:10.48550/arXiv.1405.6974> are included. An iterative\nsearch method using generalized simulated annealing\n(Bohachevsky, Johnson and Stein, 1986)\n<doi:10.1080/00401706.1986.10488128> is also included.",
